I am semi obsessed with the highboys wearing the Coker STA Super Lugs...about a 36" pizza cutter.
sta super lugsso there may be more options if you play around in the Coker website for these old school pizza cutters
have read some guys run them on their snow plow trucks, air down, and something else...I digress, happy digging, but you can get new old school tires from Coker also, google the highboy trucks, most are wearing these 36.3" bad boys
